How to Choose the Right Self Storage Unit Size | BIG Storage

Not sure what size self storage unit you need? You're not alone. Choosing the right storage unit size is one of the most common questions we hear at BIG Storage. Rent too small and you'll be cramming boxes in the door. Rent too large and you're paying for space you don't use. This guide will help you find the perfect fit at any of our Mississippi Gulf Coast locations.

Why Storage Unit Size Matters

Picking the right size upfront saves you money and hassle. At BIG Storage, we offer a variety of unit sizes to accommodate everything from a few boxes to the contents of an entire home. Here's a breakdown of our most popular sizes and what they're best suited for.

5x5 – Small Unit (Think: Large Closet)

A 5x5 unit is about the size of a small walk-in closet. It's perfect for storing seasonal items, holiday decorations, sports equipment, a few boxes of documents, or small furniture pieces like nightstands and end tables. If you're just decluttering a bedroom or home office, this is a great starting point.

5x10 – Medium-Small Unit (Think: Large Bathroom)

With 50 square feet of space, a 5x10 unit can hold the contents of a studio apartment or a one-bedroom apartment without large furniture. Think mattresses, a dresser, several boxes, a bike, or small appliances. This size is also popular among college students heading home for the summer.

10x10 – Medium Unit (Think: Half a Garage)

A 10x10 is one of our most popular sizes. It's the equivalent of a one-car garage and can handle the contents of a one- to two-bedroom apartment, including larger furniture like sofas, dining tables, and bed frames. It's also a great option for businesses storing inventory, equipment, or files.

10x20 – Large Unit (Think: Standard Garage)

Need to store the contents of a two- to three-bedroom home? A 10x20 unit gives you 200 square feet of space, enough for large appliances, multiple bedroom sets, living room furniture, and boxes from every room. It's also suitable for storing a car, truck, or boat.

Tips for Estimating What You Need

Still unsure? Here are a few tips to help you size up:

Make a list of everything you plan to store, including large furniture items. When in doubt, go one size up — you'll appreciate the extra room to organize and access your items. Think vertically: shelving and stacking boxes can maximize a smaller unit. If you're storing items long-term, make sure fragile or valuable items are protected from humidity (Gulf Coast summers can be hot and humid!).
